Valve are on a spree when it comes to game updates lately. This time Portal 2 is getting some love:

Since its release on the PC and Mac in May, 2012, community map makers have used the Steam Workshop and Portal 2's in-game editor - called the Perpetual Testing Initiative - to create and share more than 170,000 single-player test chambers. With this update, the community will for the first time be able to design puzzles that require two players working cooperatively to solve.

This update also introduces a "Quick Play" feature, which allows players to quickly access the top-rated maps in various categories.

To help players find a co-op partner, Valve is giving every current owner of Portal 2 a Steam coupon for 75% off a copy of Portal 2, which can be given away to other Steam users.

Valve has announced a free update to Portal 2′s in-game puzzle maker which now allows users to publish their own co-op test chambers. This is quite an amazing achievement and shows Valve’s dedication in enhancing their game and increasing the userbase.
